1.3.9 Protected Communications
This is administered by CNC where dial-up sites are used and only establishes communications with a
door controller if the master key code from the CNC is recognized.
When selected at the door controller, this feature is 'self-programming' and:
• Allows the next dial-up by the CNC to be accepted.
• Stores the master key sent by the CNC in the door controller.
When the CNC next dials the master door controller, the controller will only establish communications if
the CNC sends the same master keycode as is stored in the door controller.
To set this feature, see Section 7.2.2.
1.3.10 Remote Acknowledgement
Only on PC administrated systems. All alarm events generated at the controller are not cleared until an
operator has accepted them at a PC.
Whenever an alarm occurs at the controller, a relay is set. When the alarm is acknowledged at the PC
and successfully communicated back to the master controller, the relay is reset.
When using a PC, it is possible to set alarms so that the relays are not reset until an operator accepts the
alarm at the PC. This is particularly important if you are going to use the more extensive relay
programming now available.
To set this feature, see Section 7.2.2.
1.3.11 Transaction Filtering
On busy systems, performance can be improved by filtering out the less important transactions such as
request to exit, free exit, etc. Now there are 5 groups of transactions that the door controller can 'forget',
i.e. not send to the administration system.
To set this feature, see Section 7.2.1.
1.3.12 Multiple Reader Formats
Readers with Wiegand output can be connected directly to the door controller (see Section 5.2.7 for
details).
Note
When connecting Wiegand readers directly to the controller channel only one reader per channel is
allowed. To connect two Wiegand readers to a controller channel use a Wiegand interface unit per
reader. For more information contact PAC Portico Technical Support.
1.3.13 Anti-Passback
Anti-passback is a security feature that prevents a single key being shared between multiple users. This
commonly occurs when one user accesses an area and then either holds the door open or passes the
key back so that other users can gain entry.
Once the anti-passback option is applied to an area bordered by access-controlled doors, each user
having entering the area must exit it using their key. Failure to do so may result in the user not being able
to regain entry to the area.
Local, timed and global anti-passback are available and these are described in the following sections.
1.3.13.1 Local Anti-Passback
Local anti-passback is anti-passback that is controlled by one controller that records which keys have
been used to enter an area. This information is then used to determine whether or not a key can be used
to enter or leave the area. This can be used to prevent keyholders passing their keys to others to gain
entry.
Local anti-passback only operates between the doors on a single door controller with specific readers
allocated as entry (“doors” 1 and 2) and exit (“doors” 3 and 4), see Figure 3.
